Buyers Guide: Factors to look for while shopping for a window air conditioner
? Cooling Capacity
This must be a factor that you should first consider for you to pick the best air conditioner. Its capacity to cool the room is expressed in British Thermal Units and the higher the BTU then it can cool a bigger room.
A lower BTU will run for long when cooling a large room hence consuming more energy while a very big BTU will not evenly dehumidify and cool your room. For a perfect air conditioner makes sure you first calculate the size of the room in square feet then compare with the BTU.

? Things to consider in getting a proper estimate:
-If the ceiling height is above 8 feet then increase the BTU level.
-In case the room is always sunny during daytime increase BTU by ten
-For additional person occupying the room, make sure to increase it by 600 BTUs
-If you intend to use it in the kitchen make sure that the capacity is increased by 4,000 BTUs.
? Energy-Efficiency
They are cheap and last for long. Make sure to look for the Energy Star rating or the ERR number to determine its energy efficiency. Energy star rated air conditioner uses less energy, therefore, saving you money. For control of the energy use, it usually comes with cooling speeds, digital thermostats, and programmable timers.
The Energy Efficiency Ratio will indicate the amount of BTU the unit uses. A higher ERR means that the air conditioner is more efficient.

? Installation
Most window air conditioners fit inside standard windows that double hung although some can be installed in a wall provided that it has the necessary hardware. It is best if the window is too large or too small.
For the window measure both the dimensions and width inside for you to compare with the measurements stated in the air conditioner. If it does not fit well then do not worry because the installation kit has side curtains that will cover the excess space.
If you intend to install it in the wall then make sure it is designed for walls and has an installation kit. Measure the dimensions of the open wall to help you compare it with ones specified in the air conditioner.
? Electrical Requirements
Most window air conditioners are usually powerful than the appliances in your house. We recommend you to first check your electrical systems to make sure it meets the required electrical system by the unit.
If you want an air conditioner with less than 15,000 BTU then check for 115 to 220-volt circuit but if above 15,000 BTU then you will have to do a special wiring.
? Maintenance
For good and lasting performance, you must regularly maintain your window air conditioner to make sure that debris and dirt do not accumulate inside which might otherwise interfere its operation.
Clean it at least once per year to make sure it lasts for long. It is always convenient if your air conditioner has a sliding chassis since it will be easy o clean. Use water and mild soap to clean it.
